My friend has a sts that acted like it ran out of gas. After a few times of trying to diagnose it I brought over my dtc reader and got the code p0615 for the starter relay. The relay is fine, is there anything else that would cause this code to come up. The starter will turn but the engine won't crank. Any Ideas? Maybe the security system has it locked? Thanks

 

Anybody got any ideas at all? I'm at a stand still on this, any idea could help. Thanks

 

did u check power to 2 sides of the relay
and power leaving the relay
power the the starter
is the security light on
